San Francisco in the 50s was a paradise. Marin Co was more of the same. I speak from experience. The rot set in with the hippie invasion of haight-ashbury and went down hill from there. In spite of it all San Francisco is beautiful.

Wait a minute...back in the 70s wasnt it the concencess that aerosols got us into this mess in the first place. Im confused. My suggestion is send someone to hit the dimmer switch on the sun...if they go at night then no one gets hurt. Seems a simple solution to me.
